Troy-Bilt STORM Series Benutzerhandbuch

If the snow thrower fails to drive with the drive control 
engaged, and performing the drive control cable adjust-
ment fails to correct the problem, the friction wheel may 
need to be replaced. Follow the instructions below. 
Examine the friction wheel for signs of wear or cracking 
and replace if necessary
•  Place the shift lever in third Forward (F3) position.
•  Drain the gasoline from the snow thrower, or place a 

piece of plastic under the gas cap.

•  Carefully pivot the snow thrower up and forward so 

that it rests on the auger housing. 

1.  a. Remove the frame cover from the underside of 

the snow thrower by removing four self-tapping 
screws which secure it, Figure 6-13.

  b. Remove the right-hand wheel by removing the 

screw and bell washer which secure it to the axle. 

2.  Carefully remove the hex nut and washer which 

secures the hex shaft to the snow thrower frame and 
lightly tap the shaft’s end to dislodge the ball bearing 
from the right side of the frame, Figure 6-14.

3.  Carefully position the hex shaft downward and to 

the left before carefully sliding the friction wheel 
assembly off the shaft, Figure 6-15.

NOTE: If you’re replacing the friction wheel assembly 
as a whole, discard the worn part and slide the new part 
onto the hex shaft. Follow the steps above in reverse 
order to reassemble components. If you’re disassem-
bling the friction wheel and replacing only the rubber 
ring, proceed as follows:
4.  Remove the four screws which secure the friction 

wheel’s side plates together, Figure 6-16.

•  Remove the rubber ring from between the plates.
•  Reassemble the side plates with a new rubber ring.
•  Slide the friction wheel assembly back onto the hex 

shaft and follow the steps above in reverse order to 
reassemble components.
